# Manage Callbacks

Envelope callback is a functionality that allows you to receive a notification at the respective URL when an envelope appears in the mailbox according to configured filters. You can set up callbacks for mailboxes to receive envelope notifications outside our platform. This is done via API.

### Open callbacks

1. Navigate to Callback tab in the admin panel.
2. In the drop-down list, select the mailbox whose callbacks you want to display.

A list of callbacks will be displayed for the selected mailbox if callbacks have been configured via the API. Otherwise, the page will be displayed as an empty folder.

### Callback list columns
